Each magnetizer is wound around by a winding, and has two magnetizing blocks oppositely mounted on two ends of the magnetizer to correspond to a corresponding pair of permanent magnets. When the rotor unit is rotated, a magnetic field passes through the magnetizing blocks and the winding on each magnetizer to generate power. The electric generator is a single-phase or multi-phase electric generator depending on whether a pair number of the permanent magnets is or is not equal to a number of the magnetizers. As having multiple magnetizers and multiple windings, the stator unit can increase a total magnetic flux passing therethrough for the electric generator to generate more power.
